Just had a check engine light come on in my 2016 Tundra. Have tried disconnecting the battery to do a reset with no change. Going to call the dealership tomorrow and book an appointment. Question is should I disconnect my Hypertech before taking the truck to the dealership?

After my night shift, the engine light is out. Stopped by a local garage and the only code we could find is a permanent mass air flow problem. I am assuming it is from the install of the hypertech. Anyone know if you can delete permanent codes?

Yes disconnect the hypertech if you are taking it in. Might want to find a code reader. If it is the P0101 it is common and Toyota wont be able to do anything but waste money trying to find a solution.
